(i) Uncontrolled access can lead to the introduction of malware, viruses, or other malicious software onto the network, compromising the security of the school’s systems and data.
(ii) Without proper filtering or restrictions, students may access inappropriate or harmful content, which can be detrimental to their education and well-being.
(iii) Excessive use of bandwidth for non-educational purposes, such as streaming videos or gaming, can slow down the network and affect the performance of educational tools and resources.
(iv) Uncontrolled access may result in the unintentional exposure of personal information or sensitive data, posing privacy risks for students and staff.



(i) Use filtering software to block access to inappropriate websites and content categories, ensuring that students can only access educational resources.
(ii) Install firewalls and robust security software to prevent malware, viruses, and other cyber threats from infiltrating the network.
(iii) Implement bandwidth management tools to prioritize educational applications and limit the bandwidth available for non-educational activities, thus preventing network congestion.
(iv) User Authentication



(i) Security
(ii) By requiring authentication, the school can track and monitor user activities, enabling accountability for any misuse or violations of acceptable use policies.
(iii) Personalization
(iv) User authentication helps the school comply with regulations and standards related to data protection and privacy by controlling access to sensitive information and ensuring proper user authentication measures are in place.


(i)Access to vast amounts of information for research and learning.
(ii)Facilitation of communication and collaboration among students and teachers.
(iii)Provision of online resources and tools for interactive learning experiences.
(iv)Flexibility in learning schedules and access to online courses and materials.

(i) Corrective maintenance involves fixing errors or defects in software or hardware after they have been detected.
(ii) Adaptive maintenance refers to making changes to software or hardware to keep it usable in a changing environment or with new requirements.

File organization is the way data is stored and arranged in a file system to facilitate efficient retrieval and storage of information.

– Sequential File Organization:
II. Records are inserted one after the other.
– Direct (Random) File Organization:
IV. It generates random key to identify location.
– Indexed File Organization:
I. It does not support the use of tapes.
– Hashed File Organization:
III. It does not generate random keys to identify location.

3a. Personal
II. Mainframe
Iii. Super

3b In tabular format

Analog Computers:

– Use continuous physical phenomena (e.g., voltage, current, position) to represent information
– Process information in a continuous range (e.g., 0-10 volts)
– Typically use analog circuits and mechanical components
– Examples: slide rules, analog clocks, thermometers
– Advantages: fast, simple, and intuitive for specific tasks (e.g., scientific calculations)
– Disadvantages: limited precision, prone to noise and interference

Digital Computers:

– Use discrete values (0s and 1s) to represent information
– Process information in a discrete range (e.g., 0 or 1, true or false)
– Typically use digital circuits and microprocessors
– Examples: smartphones, laptops, calculators
– Advantages: high precision, flexible, and scalable
– Disadvantages: slower than analog for specific tasks, require complex programming
